Application December 1 'l 15 Claims.

The present invention relates to the manufacture of hosiery and, more particularly, to an improved fiat or full-fashioned knitting machine adapted to knit heel tabs directly into a combination leg and foot stocking blank, and to an improved method of knitting heel. tabs into such a blank. l I

It is the principal object of the invention to provide mechanism capable of knitting heel tabs simultaneously and in opposite directions as continuations of the high heel sections of a combination leg and foot blank and, during the knitting of said heel tabs, of transferring loops of the sole sections of said-blank for interlooping connection with the loops at the inner selvedges of the heel tabs, and of transferring certain loops at the outer selvedges of said heel tabs to narrow and shape the same.

3 Heretofore, because of the standard construction and operation of known knitting machines, it has been customary in knitting heel tabs into a combination leg and foot blank, to lay the yarns by means of yarn carriers operating simultaneously in the same direction and, during the knitting of said courses, to transfer by means of transfer point combs, loops of the first course of each sole section into engagement with the loops at the inner selvedge edge of a completed course of each heeltab. However, it has been foundthat in such a mode of operation, one or the other of the carriers unavoidably remains in the way of the transfer points, thus interfering with the proper operation of the latter.

Therefore, it is an important object of the present invention to provide mechanisms functioning to operate the carriers in such a manner that the yarns intended to form the heel tabs are laid simultaneously in opposite directions, and to operate the transfer points at every other course 'when the carriers have reached the outer selvedge edges of the heel tabs so that said points may operate without interference. I

It is also among the main objects of the i nvention to provide corelated mechanisms operable to knit heel tabs simultaneously in opposite directions as continuations of the high heel sections of a combination leg and foot blank, to transfer the marginal loops of the sole sections of said blank for overlapping, interlooping connection with certain loops at the inner selvedges of every other courseof said heel tabs, and to transfer certain loops at the outer selvedges of said heel tabs to narrow and shape the same, said mechanisms being respectively associated to cofunction in predetermined timed relation.

, 1938, Serial No. ammo (o1. ss-szi 5 Another important object of the invention resides in the provision of mechanisms adapted to knit heel tabs into a combination leg and foot blank by knitting simultaneously in opposite directions the heel tabs directly onto the leg portion of the blank, and interknit the selvedge edges of every other courseof the heel tabs into the adjoining portion of the foot fabric to form a finished blank.

The invention is moreover characterized by the fact that the mechanical realization thereof may be had through a novel combination of parts easily and readily adapted to operatewlth an ordinary well known footer knitting machine, without necessitating material changes in the basic construction and operation thereof.

It is also a characteristic feature of the invention to provide a simplified arrangement of co-related mechanisms which may be conveniently and easily combined with a standard footer knitting machine for converting the same into a heeling machine embodying knitting elements operable simultaneously and in opposite directions for effecting the knitting of heel tabs and interknitting overlapping connections between said heel tabs and adjoining portions of the leg blank. I

With these and other objects in view, as may hereinafter appear, the several features of. the invention and the advantages to be obtained thereby will be readily understood by those skilled in the art from the following description taken in conjunction with the accompanying drawings, in which: I

. be derstood that I have shown only them parts of a full-fashioned hosiery knitting machine which are essential to the clear understanding of the present invention. The basic structure of the knitting machine itself, as reproduced in the drawings. is that of the commonly used "Reading full-fashioned footer with which anyone skilled in the art is well acquainted. I

I In the drawings illustra the preferred construction of the improved knitting machine, the usual machine frame is indicated at 20 and carries a center bed 22 about which are mounted a plurality of spaced knitting sections, designatedin their entirety for. convenience herein bythe reference character 24- (Figure 3). Each knitting section 24 essentially comprisesa needle bar. 26, knock over bits 28, and sinkbrs and dividersdll. The thread or yarn is rest the knittingsections 24 by means of carriers 32 depending from the carrier rods 3-: mounted for reciprocation in the carrier rod brackets 36.

The needle bar 26 carries the needles 38 divided into three groups, that is, two end groups 39 and an intermediate group 39' (Figure 5). The needles on the end groups are adapted to receive the yarn from the carriers 32 and act to hereinafter.

knit the fabric, whereas the needles in the intermediate group '39 are non-knitting, and serve only to retain the loops of a previously knitted fabric for the purpose to be explained in detail.

Disposed for cooperation with a predetermined number of needles in the knitting needle groups secured. to separate narrowing bars 52 and S4 which are also sliddblymounted in said brackets 41.

The narrowing combs 40 and 42 are intended to operate independently of the loop transfer combs 4.. and II and, for that purpose, two.

separate and distinct m are utlized. One mechanism, which may be the usual well ratchet device it operatedin tion from the 2,198,052 I known narrowing mechanism, is operativly asso-- ciated with the narrowing bars 44 and 46 to impart a longitudinal sliding movement thereto, while the other mechanism, which has been devised especially to control the loop transfer mechanism, is" associated with the bars 52 and 54 to impart a longitudinal reciprocating movement thereto.

As shown in Figure 1, the narrowing motion mechanism comprises a pair of narrowing nuts '56 and 58 respectively engaged-with a double threaded spindle 60 rotatably carried on the machine frame so that, upon rotation of said spindle, the narrowing nuts will travel in opposite directions, as indicated by arrows A and B. Each narrowing nut is provided with a flange I2 engageable with stops 64 on the narrowing bars 44 and 46. In this manner, it will be understood that said narrowing bars 44 and 46, with their A narrowing combs 40 and 42, will follow the movement of the corresponding narrowing nuts when the spindle 60 is rotatedduring a narrowing cycle of the knitting machine. During such cycle, the

I'OtflflOIhOf the spindle is accomplished automatically through actdation, of a pawl and the usual well known manner. M t

The transferring motion mechanism comprises a cam disc" having cammlng faces III on both of its sides and mounted for oscillation on a rotating shaft 12 suitably fixed in brackets 13. Disposed for riding engagement with the camming faces 10 of the cam disc 68 isa pair of fingers I4 carried by sleeves It slidably mounted m: the shaft I2, each sleeve being provided with a forked extension Ill engaging a second shaft 12 also suitably fixed in the supporting brackets 13 and adapted toguide said sleeves in their sliding movements. The sleeves 'li are' further :provided w'lth projections. 84 engageable with adjustable stop elements ll, one of said elements being secured to the transfer bar 52 and the other element being secured to the transfer bar 54. The fingers 14 are constantly urged into riding en-' gagement with the camming faces ll of the cam disc I! by means of springs 88 conveniently connected to thebars 52 and I4 and to parts of their supporting structures, such as the brackets 41.

The cam disc 68 is actuated by'means of a linkarrangement consisting of pivoted levers ill connected to an arm l2 of a sleeve 94 rotatable on the transfer mechanism supporting shaft 85.

The sleeve 84 is formed with-a second arm Q! 'connectedto a rod 98. intum connected to one arm- Ill of a bell. crank lever-"I02 arranged for oscillation on theback narrowing shaft "4 of the machine frame. The bther arm I06 of the bell crank lever "2 is attached to a rod Ill pivoted to a rocking lever ll. carrying a roller 2 disposedfor coaction with a pattern cam 4 on themain cam shaft III in the manner to-be'v described more fully hereinafter.

is Because of this construction, it will be understood that, upon oscillation of the cam disc 68', the transfer bars Hand 54 will be caused to move in opposite directions, asindicated by the arrows C and D in Flgure'5.

The elements so far described receive their monow be described. v As illustrated in the drawings, the-main cam parts of the machine'which willv shaft 6 supported in bearings on the machine frame "carries in addition to the pattern cam -l l4 a e presser cam i-llf'a'. needle bar cam "I, a wing headactuating cam l22 at each end of the machine, a narrowing dip cam I24, shogging cams I28 and a face cam I80 for preventing operation of the narrowing mechanism.

The needle presser cam I I8 operates'a follower I82 on a rocker arm I84 and a needle bar fork I88 to impart the usual longitudinal movement to the needle bar. The needle bar follower I88 on a cam lever I88 is operated by the needle bar and I88 to operate the needles for knitting, and each narrowing head actuating cam' I22 is in inactive relation with a' follower I48, whereby no narrowings are effected. Conversely, in the other shifted position of the cam shaft, the needle/pres ser cam I I8 and the needle bar cam I20 are in inactive relation to the followers I82 and I88 whereby no knitting takes place when each narrowing head actuating cam I22 is in active relation to its follower I48 to produce narrowings, and thus shape the fabric being knitted.

Each narrowing head actuating cam follower I48 is mounted on a lever I50 pivotally mounted at one end of the machine frame and pivotally connected by a pin I52 onto the lifting lever I54 adapted to operate the narrowing mechanism by means of the ratchet device 85.

It is to be ,understood that this mechanism is that usually provided on the knitting machine for variably moving the narrowing combs of'each section towards and away from each other to operate theparrowing points thereof, and to vary the travel of the carrier rods supporting the yarn carriers in the usual manner, the ordinary end stops I54 being provided for that purpose.

In accordance with the present invention, and as clearly shown in Figure 3, the jacks I55 for actuating the sets of sinkers associated with the knitting needle groups 88 are operated by separate slur cams I55 and I58 respectively carried by slur cock boxes I50 and I52 individually connected to slur cock bars I54 and I88.

One slur cock bar I84 is rigidly connected through a bracket I58 to the long arm I10 of the Coulier motion mechanism I12 to receive a longitudinal reciprocatlong movement therefrom. The remaining slur bar I85 is operatively connected to the firstmentioned slurcock bar I84 by means of gearings I14 operable to transmit motion to said remaining slur cock bar I58 in a direction opposite to the 'slur,cock.'bar- I84 connected with the long arm I10 of the Coulier motion I12. The gearings I14, as shown in the drawings, preferably consist of a rack I15 afflxed to the slur cock bar I84, a rack I18 affixed to the slur cock bar I58, and a pinion I supported by means of a bracket I82 mounted upon the center bed 22 of the machine frame. The bracket also preferably carries rollers I84 and I85 respectively disposed to engage the slur cock bar I84- and I85 to assure proper engagement of the racks I18 and I18 with the pinion I80.

Also in accordance with the invention, the car rierbars 84 supportingv the yarncarriers 82 associated with the knitting needle groups 88to feed rate friction boxes I88 and I81 respectively mounted on separate friction rods I88 and I88.

One friction rod I88 is connected by means of a bracket I88 to the long arm I10 of the Coulier motion to receive longitudinal reciprocating movement therefrom, The other friction rod I08 is operatively connected to the friction rod I88 by means of gearings l80ioperable to transmit motion to said rod I88 in a direction opposite to that of the rod I88. The gearings I80, as shown in the drawings, particularly Figures 8 and. 10 thereof, consist of a rack I82 rigidly secured to the friction rod I88, a rack I84 rigidly-secured to the friction rod I88, and a pinion I88 suitably supported between the racks I82 and I84 for engagement therewith. The'gearings I80 may be enclosed in a housing I88 suitably mounted on the machine frame. in active relation to their respective followers I82 From the foregoing description of the slur and yarn feeding mechanisms, it will be appreciated nism I12, the slur cock I50 and the yarncarrierfl associated with one of the knitting needle groups 88, and the slur cam I82 and the yarn carrier 82 associated with the other knitting needle group 88', are caused to move in unison towards and away from each other, thus laying the yarns and actuating the sinker's simultaneously in opposite directions during the knitting cycles of the machine. In this manner, it will be appreciated that, at every other course knitted on the knitting needle groups 88, the carriers become positioned at the outer ends of the needle bar and, accordingly, are moved away from the loop transfer combs 48 and 50 which may then operate without interference during the loop transferring cycles of the machines.

The operative change of the machine to and from the knitting and loop transferring cycles is accomplished automatically by means of apattern control mechanism, designated in its entirety for convenience herein by the reference character 200.- This mechanism 200 is of the usual well known construction and includes the pattern chain 202 provided with a series of buttons. the function of which controls the mechanism to cause'the shifting of the main cam shaft H5. The shifting of the main cam shaft brings thenarrowing dip cam I24 in position for en- Easement with a'follower 204 carried by the lever system 208 to impart to the entire loop engaging and laterally transferring mechanism its dipping motion. The shifting of the 'main cam shaft also brings the pattern cam H4 in position for cooperation with the follower II2 to actuate the transfer bars 52 and 54 in the manner hereinbefore stated.

Although the shifting of the main cam shaft causes the dipping motion of the loop engaging and laterally transferring mechanism,- and causes the actuation of the transfer rods 52 and, the narrowing motion mechanism remains inoperative because it is necessary that the follower I 48 be also shifted in order that id narrowing motion mechanism may operate. For that purpose,

the pattern chain 202 is provided with a second set of buttons acting on a lever 208 connected to to a link arrangement 2I0 cooperating-with the face cam I80 to slide a rod 2I2 having a forked member 2 connected thereto, which engages the follower I48 to shift the same to a position that, with actuation of the Coulier motion mecha- From-the foregoing, it will be appreciated that the loop transfer mechanism may operate when the narrowing mechanismis idle, or that both mechanisms may operate simultaneously.

As hereinbefore stated, the machine is devised to knit heel tabs into a combination full-fashioned leg and foot blank. Such a blank has been shown in Figure 11. Asishown in Figure 11,

. the blank 220 comprises a leg'222 having reinforced high heel portions 224 and ,a foot=22l having reinforced sole portions 228 which are formed by continuous knitting into the combination leg and foot blank.

Between the leg and foot portions of the blank,

as best shown in Figure 12, two partial non-reinforced courses 2 are provided which serve form a line of demarcation between those tions of the last course of the foot fabric and the first course of the sole fabric intowhich the heel portions are subsequently to be knitted. During the knitting of the partialcourses referred to, the knitting with a reinforced yarn is continued on a restricted immber of needles so that a reinforced selvedge loop 232 is provided at the inner ends of the partial non-reinforced connectingcourses 2" to form the heel corner of the finished blank.

and two additional point sections, designated respectively at 2 and 242, which are arranged in parallel relationship, as shown in the diagrammatic Figure 12, that is, in substantially the same Positions in which the fabric loops appear in the combination blanks It will be noted that the topping operation,

as described, is carried out prior to thecutting or removal of the partial non-reinforced courses 2 so that when the high heel and sole portions ofthe fabric are separated, all of the disengaged fabric loops are supported by the topping points to prevent any possibility of dropping the loops.

In accordance with the preferred form of applicants method, the loops forming the'partial courses 2. may be severed by means of a cutting knife 2 to permit the separation of the two parallel topping point sections and the loops supported thereon, which are then moved outwardly into a straight line relationship in which all of the points are spaced to register with the quills of a transfer bar, which may be of the ordinary description and utilized for transferring the fabric loops from the topping points to the needles of a heel knitting machine, as represented 'inrigure 13.

. In knittingthe heel portions, the carriers 32 are actuated simultaneously and in opposite dirations to lay the yarns across the active knitting needles so as to knit the courses *2 (Figure 14) of the heel portions 2". During thef'knitting of said heel portions, the loops 238 of the first courses of the sole portions 22. are gradually transferred from interknitted engagement with struction of the several parts herein shown and described is capable of certain modifications and,

therefore, any modification coming within the scope of the subjoined claims is to be considered within-the spirit of the invention.
